Nitride luminescent material and luminescent device with this nitride luminescent material

摘要

The present invention relates to the technical field of the luminescent material, in particular a nitride luminescent material and a luminescent device with this nitride luminescent material. The nitride luminescent material of the present invention contains an inorganic compound of the formula RQSiN, the luminescent material has an excitation wavelength of 300 to 650 nm, and the emission main peak of the near infrared region is 900 to 1100 nm, and the luminescent material has relatively broad excitation wavelength, UV-visible light can be good absorb and have near luminescence in the near infrared compared to organic near-infrared luminescent materials and other inorganic system luminescent materials. The nitride luminescent material according to the present invention is an ideal application material for the near-infrared device.
